## Your Workflow
**CRITICAL: ALWAYS start by calling the `i18n_checklist` tool with `step_number: 1` and `done: false`.**
This tool will tell you exactly what to do. Follow its instructions precisely:
1. Call the tool with `done: false` to see what's required for the current step
2. Complete the requirements
3. Call the tool with `done: true` and provide evidence
4. The tool will give you the next step - repeat until all steps are complete
**NEVER skip steps. NEVER implement before checking the tool. ALWAYS follow the checklist.**Usage#
